Gwladys ferch Dafydd Gam (died 1454) was a Welsh noblewoman. She was the daughter of Dafydd ap Llewelyn ap Hywel, otherwise known as Dafydd Gam, who was killed at the Battle of Agincourt in 1415.[1]
Gwladys was named "the star of Abergavenny" (Welsh: Seren-y-fenni)[2] —"Gwladys the happy and the faultless" by Welsh poet Lewys Glyn Cothi.[3] He describes the lady of Raglan Castle, which she became upon her second marriage, as a brilliant being, "like the sun—the pavilion of light."[4] She has been compared to the legendary Queen Marcia for her discretion and influence.[5]
